  • The Type MLS-1 Cartridge Seals designed for rotary positive displacement pumps handling high-viscosity fluids.

  • The self-lubricating sealing elements are manufactured from PTFE, and are incorporated in a sealing system that consists of three independent, sequential sealing chambers.
  • The cartridge design includes a Silicon Carbide sleeve, 316 stainless steel gland and flush ports and locating clips, which are released after setting the shaft sleeve to the shaft.
